Brief Summary:
A randomized controlled clinical multi center trial to assess the efficacy of a combination of autologous mesenchymal stem cells and biomaterial in jaw bone regeneration prior to dental implant placement in comparison to standard autologous bone block grafting.

Condition or disease Intervention/treatment Phase
Alveolar Bone Atrophy Combination Product: Advanced medicinal Therapy (MSC combined with biomaterial) Procedure: Autologous bone graft Phase 3

Detailed Description:
A phase III multi center clinical trial, randomized and controlled.The study subject is lacking one or more sheet behind the canine in the upper or lower jaw, and the alveolar ridge is too narrow to place a dental implant. The test objects will have augmentation using autologous mesenchymal stromal cells and a biomaterial, biphasic Calcium Phosphate. The control is the traditional bone block from the ramus.

Arm Intervention/treatment
Active Comparator: Control
The gold standard; Bone block from the ramus of the nation will be transplanted to the alveolar ridge.
Procedure: Autologous bone graft
Augmentation of the alveolar ridge with bone graft

Experimental: Test
Expanded, autologous mesenchymal stem cells in combination with biphasic calcium phosphate
Combination Product: Advanced medicinal Therapy (MSC combined with biomaterial)
Augmentation of alveolar ridge with MSC and biomaterial

Primary Outcome Measures :
  1. Change in bone width [ Time Frame: 0-5 months ]
    Changes in linear measurements of bone width measured by CBCT.Principal assessment is linear change in bone width 2 mm below alveolar crest measured by means of CBCT images from baseline to 5 months after the regenerative surgery, immediately prior to implant placement

Secondary Outcome Measures :
  1. Pain postoperatively in the two different treatments [ Time Frame: 21 months ]
    Assessed by VAS scale, the scale goes from 0 to 100, 100-mm horizontal line on which the patient's pain intensity is represented by a point between the extremes of "no pain at all" and "worst pain imaginable."

  2. Radiological examination of bone volume [ Time Frame: 21 months ]
    To evaluate the formation of the new bone by assessing if it is possible to insert an implant in the reconstructed area 5 months after the grafting procedure. This decision will be made based on radiological examination of bone volume by means of 3D CBCT images captured immediately prior to implant placement, 5-6 months after the regenerative surgery.
